We drove around a bit and he showed us a few phone switching centers (Southfield Main, Warren Main, a satellite office in Roseville, and a few others). It was cool. We swapped phone numbers so maybe we'll have more interesting times :-) (I have very few real life friends)
Anyway I am in the process of writing this badass site where you can type in an area code and prefix and learn all kinds of cool shit about it, that'll be fun.
I'm at work now.
